Diamond PosiStop LTS Filter Pipette Tips 200µL 96/Rack Globe

Description

Product Overview

Diamond PosiStop LTS filter pipette tips are engineered to meet the rigorous demands of modern molecular laboratories. Manufactured by Globe Scientific in a state‑of‑the‑art 100k cleanroom, each tip is formed from medical‑grade virgin polypropylene that contains no metal impurities, ensuring chemical inertness and compatibility with a wide range of reagents. The tips are sterile, RNase‑free, and certified free of DNase, pyrogens, PCR inhibitors, and endotoxins, providing a contaminant‑free environment for sensitive applications such as qPCR, next‑generation sequencing library preparation, and clinical diagnostics. With a precise 200 µL graduated volume and a positive‑stop LTS design, the tips create a reliable seal that eliminates dead‑volume leakage and improves dispensing accuracy. They are supplied pre‑racked in 96‑tip racks, allowing rapid loading into compatible pipettors and reducing set‑up time. The packaging dimensions of 14 × 7.5 × 5.25 inches and a weight of 2.6 lb make bulk handling straightforward while maintaining sterility throughout the supply chain.

Usage

These filter pipette tips are optimized for use with Diamond PosiStop and Rainin LTS‑style pipettors, but they also perform reliably with other LTS‑compatible models. Researchers in academic, biotech, and clinical settings will find them especially valuable when working with nucleic acid extractions, enzyme reactions, and high‑throughput screening assays where cross‑contamination must be avoided. The 200 µL capacity is ideal for medium‑volume transfers, enabling precise aliquoting of reagents, standards, and samples. Because the tips are pre‑racked, laboratories can keep a ready‑to‑use inventory on the bench, minimizing the risk of accidental tip contamination and streamlining workflow during time‑critical experiments. The robust polypropylene construction tolerates repeated autoclave cycles, making them suitable for protocols that require tip reuse after sterilization. Whether you are preparing PCR master mixes, performing ELISA washes, or conducting cell culture media exchanges, these tips provide consistent performance and help maintain the integrity of your data.

Why Choose Us

Globe Scientific’s commitment to quality is reflected in every aspect of these filter pipette tips. The manufacturing process incorporates advanced automated dispensing and filtration technologies that guarantee uniform tip geometry and reliable filter performance across the entire batch. Each tip undergoes rigorous testing for endotoxin levels, RNase activity, and particulate contamination, ensuring that the final product meets or exceeds industry standards for molecular biology applications. The positive‑stop LTS design reduces the likelihood of tip slippage and provides a tactile cue that the pipette has reached the intended volume, which is particularly beneficial for users who require repeatable precision. In addition, the sterile packaging is designed to protect the tips from environmental exposure, preserving their purity until the moment of use. Globe Scientific also offers responsive technical support and a comprehensive warranty program, giving customers confidence that any issues will be addressed promptly. By choosing these tips, laboratories benefit from a combination of superior material quality, validated performance, and dedicated after‑sales service that together enhance experimental reliability and productivity.

FAQ

Are these tips compatible with all LTS pipettors?

Yes, the tips are specifically engineered for Diamond PosiStop and Rainin LTS pipettors, but they also work with other manufacturers that follow the LTS standard. The positive‑stop feature and tip dimensions conform to the LTS specification, ensuring a reliable fit and seal across compatible devices.

What level of sterility is guaranteed?

Each tip is supplied sterile and has been tested to be free of detectable DNase, RNase, pyrogens, PCR inhibitors, and endotoxins. The manufacturing environment is a Class 100,000 cleanroom, and the packaging maintains sterility until the point of opening, making the tips suitable for the most demanding molecular biology protocols.

Can the tips be autoclaved for reuse?

Yes, the virgin polypropylene material tolerates standard autoclave cycles without deformation or loss of filter performance. This allows laboratories to reuse the tips after proper sterilization when protocols call for tip reuse, providing flexibility and cost‑effectiveness.

How does the filter protect my samples?

The built‑in filter prevents aerosol and particulate carry‑over between samples, which is critical for applications such as PCR, qPCR, and next‑generation sequencing library preparation. By trapping contaminants, the filter helps maintain assay integrity and reduces the likelihood of false‑positive or false‑negative results.

What support does Globe Scientific provide if I encounter an issue?

Globe Scientific offers a responsive technical support team that can assist with compatibility questions, troubleshooting, and performance verification. In addition, the product comes with a warranty that covers manufacturing defects, ensuring that any quality concerns are addressed promptly and professionally.
